Well, since I couldn't kill any of the processes, I tried to shut the 
system down.  It hung for several hours at "dismounting file systems" 
and I finally had to hit the reset button.

If there's anything I can do to help debug this, I'll be happy to help. 
In the mean time I'm going to try again to see if I can get a build.sh 
running - this time I think I'll try without -j4 and see if it gets any 
further.
